+| Setting | Value |
+| --- | --- |
+| Backend | vLLM |
+| Base precision | AWQ INT4 |
+| Effort | 2 |
+| Candidate-softmax temperature | 1.0 |
+| Context | 16,384 tokens |

+
+Effort 2 averages probabilities from the original and a deterministic shuffled candidate order after mapping them back to the original candidates. Multi-select uses greedy sequential labels and STOP. Reference answers are used only for scoring.

+
+## JevBench and Decision Index
+
+The additional results in [README.md](README.md) are reported on the [SurdAI release page](https://surdai.com/zh/blog/simplex-cd-release#cd-latest-results). Public 231 includes Hard 111. Decision Index 0.2.1 has a separate score scale. The linked results use their respective serving configurations; they do not establish numerical equivalence with the included CLI.
+
+## Reproduction
+
+Use the matching base model, precision, effort, and context setting when comparing results. BF16 and quantized backends are not guaranteed to produce identical predictions. The release defaults to 65,536 tokens. The reported CMDB evaluation used 16,384 tokens; use the explicit setting below to match that evaluation.
+
+```bash
+python infer.py --backend vllm --base /path/to/compatible-4bit-base \
+  --adapter . --effort 2 --max-context 16384 --prompt-format cmdb \
+  --input /path/to/inputs.jsonl --image-root /path/to/images \
+  --output predictions.jsonl
+```
+
+Use the JSON schema in `examples/`. Test the decision logic with `python -m unittest test_decision`, or validate inputs with `--dry-run` before loading weights.

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+
+[CMDB-1500 leaderboard](https://surdai.com/zh/blog/cmdb-1500#results) · [Release overview](https://surdai.com/zh/blog/simplex-cd-release) · [Dataset](https://huggingface.co/datasets/SurdAI/CMDB-1500) · [SPX-CD-Omni](https://huggingface.co/SurdAI/SPX-CD-Omni)
+
+**SPX-CD-Pro (Simplex Calibrated Decision Model)** by **SurdAI** is a LoRA adapter for **Qwen/Qwen3.8-27B** (27B dense). It supports text and image decisions: single-choice, multi-select, binary judgments, and ordinal ratings. The runner returns candidate probabilities without generating a reasoning trace.
+
+LoRA rank/alpha **32/64** · Adapter **890.7 MiB** · Context **65,536 tokens** · Up to **1,024 candidates**.
+
+Download the base model separately; this repository provides the LoRA adapter and decision runner.
+
+## Download
+
+```bash
+pip install huggingface_hub
+hf download SurdAI/SPX-CD-Pro --local-dir SPX-CD-Pro
+cd SPX-CD-Pro
+```
+
+## Run inference
+
+Use separate environments for the two backends. Install CUDA-enabled PyTorch for Transformers; install the vLLM requirements in a clean environment.
+
+**Transformers, BF16 base:**
+
+```bash
+pip install -r requirements-transformers.txt
+python infer.py --backend transformers --adapter . \
+  --input examples/text.json --output predictions.jsonl
+```
+
+**vLLM, compatible 4-bit base:**
+
+```bash
+pip install -r requirements-vllm.txt
+python infer.py --backend vllm --base /path/to/compatible-4bit-base \
+  --adapter . --effort 2 --input examples/text.json --output predictions.jsonl
+```
+
+Use a compatible 4-bit quantization of **Qwen/Qwen3.8-27B** with its matching processor. The inference backend must support both that quantization format and this LoRA adapter; 4-bit formats are not interchangeable. The exact evaluated configuration is recorded in [EVALUATION.md](EVALUATION.md).
+
+For images or multi-select, use `examples/image.json` or `examples/multi_select.json`. See these files for the input format and `python infer.py --help` for options. Image paths are relative to the input file, or to `--image-root` when specified.
+
+## Results
+
+### CMDB-1500
+
+Completed CMDB-1500 evaluation, **effort 2**, **4-bit base**, vLLM:
+
+| Scope | Questions | Accuracy |
+| --- | ---: | ---: |
+| Text | 1,200 | 79.33% |
+| Images | 300 | 88.67% |
+| All | 1,500 | 81.20% |
+
+All 1,500 questions produced valid predictions. Evaluation settings are in [EVALUATION.md](EVALUATION.md); machine-readable results are in [evaluation_results.json](evaluation_results.json).
+
+### JevBench and Decision Index
+
+The [SurdAI release page](https://surdai.com/zh/blog/simplex-cd-release#cd-latest-results) reports the following results:
+
+| Effort | JevBench Public (231) | JevBench Hard (111) | Decision Index 0.2.1 ↑ |
+| --- | ---: | ---: | ---: |
+| 1 | 89.61% (207/231) | 79.28% (88/111) | 58.30 |
+| 2 | 90.04% (208/231) | 80.18% (89/111) | — |
+
+Hard 111 is a subset of Public 231. Decision Index uses its own score scale. These results use the serving configurations described on the linked release page.
+
+## Settings
+
+- `--max-context`: default **65,536 total tokens**. Each scoring pass reserves one output token, leaving at most 65,535 prompt tokens, including image tokens, candidates, and selected-label prefixes. Reduce this setting if needed for available memory.
+- `--effort 1–5`: average distinct candidate orderings, capped at two for binary questions. Default 1; the CMDB results use 2.
+- `--temperature`: candidate-softmax temperature, default 1.0.
+- `--prompt-format`: `cmdb` for text and image decisions; `open-format` for text single-choice tasks.
+- Multi-select uses sequential labels and STOP. Images: up to five per request, with a processor pixel budget of 524,288 per image. Inputs exceeding the context limit are rejected.
+
+## License and integrity
+
+Apache 2.0 for this adapter and included code. The base model is distributed separately under its own [model card](https://huggingface.co/Qwen/Qwen3.8-27B). Verify release files with [checksums.json](checksums.json). Release identity and original weight SHA-256 are recorded in [release.json](release.json).
